Introduction

The following is an introduction to the non-customized sections. Please ensure that you don't confuse them with the customized parts.

If your host does not have an IPv6 subnet and you want to assign IPv6 addresses to containers, the host itself needs a public IPv6 address. The installation script will automatically detect and configure this.

:::warning The containerd solution does not support KVM/QEMU virtual machines. It only supports Linux containers (LXC) and is suitable for environments without KVM hardware virtualization support. :::

Project Features

Bulk or individual NAT server provisioning based on containerd + nerdctl runtime

• Installs containerd + runc + nerdctl + CNI + buildkitd via the nerdctl-full bundle
• Uses self-compiled base images (stored in GitHub Releases), with offline loading prioritized and fallback to official images
• Each container comes with 1 external SSH port, 25 consistent internal/external ports, with optional independent IPv6 address binding
• Default unprivileged containers, supports lxcfs mounting (if lxcfs is installed on the host)
• Supports disk limit parameters (requires xfs/btrfs snapshotter with storage-opt support)
• Supports China CDN acceleration
